12V Voltage Battery Panel USB Digital Display Meter For Battery Car Motorcycle Battery Monitor Meter Capacity Tester - DC 8-30V Rv Battery Monitor Battery Voltage Meter 12v 24v Digital Battery Capacity Tester Car Motorcycle Golf Cart Battery Meter with Alarm New upgrade: Battery Monitor can measure and display battery capacity, voltage, temperature, percentage. Added type c and usb interface, built-in external temperature probe can be used as temperature sensor. After setting the parameters, it has a power-off memory function, and there is no need to repeat the setting Adapter battery: The digital battery monitor is suitable for DC8-30V (12V, 48V) lead-acid batteries, ternary lithium batteries, and iron lithium batteries. The factory default battery parameters are lead-acid 1P-12V, which has a wider range of applications and can meet your basic needs to the greatest extent Safe to use: with low voltage alarm setting, input reverse connection protection, reverse connection of positive and negative poles will not burn Six modes: 3 battery types are set as lead-acid P, ternary lithium L, iron lithium F; custom setting of high and low voltage range; backlight time setting, low voltage alarm setting Wide range of applications: The battery monitor can be widely used in electric vehicles, motorcycles, golf carts, bicycles, boats and other facilities that need to monitor batteries Voltage intelligent calibration: When you need to calibrate the voltage of the meter, disconnect the power, press and hold the on/off button, turn on the power, enter the calibration mode and release the button, then long press the on/off button for 2 seconds to start automatic calibration (calibration). The letter V will flash when the calibration is completed, and the letter V will be always on after the calibration is completed); the reason for the failure of the calibration: the error of the external power supply is too large or the external power supply is not a DC30V power supply, resulting in a calibration error, please replace the external calibration power supply and re-calibrate Product parameters Voltage detection range: DC8-30V Working current: <15mA (without charging function) Display mode: LCD screen Display color: green Temperature display (optional) USB output: QC2.0, QC3.0, maximum output 18W (5V-3.4A, 9V-2A, 12V-1.5A) Typec output: QC2.0, QC3.0, maximum output 18W (5V-3.1A, 7V-2.4A, 9V-2A, 12V-1.5A) Detection accuracy: ±1% Installation size: 58.5mm*36.5mm Refresh speed: 500ms/time Appearance size: 61mm*40mm*22mm Product Description L measurement of ternary lithium battery: L03 series to L07 series (power-off memory) P measurement of lead-acid battery: DC12V, DC24V (power-off memory) Iron-lithium battery F measurement: F03 series to F08 series (power-off memory) Custom setting high and low voltage range: DC8-30V The front is the on/off button, and the back is the setting button. Please set the parameters before installing and using Mode Description On the main page, long press the on/off button for 2 seconds to enter the mode setting page, and then long press the back setting button for 2 seconds to exit the setting page and return to the main page Mode 1 -- lead acid P setting; Mode 2 -- ternary lithium L setting; Mode 3 -- Iron Lithium F setting; Mode 4 -- custom high and low voltage settings; Mode 5 -- low voltage alarm setting (alarm when the voltage is lower than this parameter); Mode 6 -- backlight time setting; first, fully charge the battery first, the saturation voltage of a series of ternary lithium batteries is DC4.2V, and a series of iron lithium batteries The saturation voltage is DC3.6V; for example: the saturation voltage shows 29.4V (7 strings), this is the ternary lithium battery, and then select the parameters according to the setting mode of the ternary lithium battery   Packing list: 1x Battery Monitor Meter Capacity Tester
